A few more changes that should help:
1. Made it easier to snap corridors to rooms and other corridors.
2. Fixed a bug where dragging a room might not correctly drag all connected corridors with it.
3. In the dialog for setting textures for the entire dungeon, textures for rooms and corridors can now be set separately.
4. You can zoom in and out with the mouse wheel.
5. If you have two corridors whose ends are connected together, you can move both ends at the same time by holding down the Ctrl key.

Edit: Okay, I fixed the bug in selecting objects and put the ZIP back up. I also added feature #5.
